Abstract
The utility model relates to a pressure-relief fire-resistant fire-extinguisher for dust-collecting system, which is composed of a joint cylinder body, core body such as a dust isolating layer, a fire extinguisher whose shape is like the Chinese character 'jing', a fence-typed fire-resistant explosion suppression device, etc. and a pressure-relief gate, wherein, the dust isolating layer, the fire extinguisher and the fence-typed fire-resistant explosion suppression device are arranged in turn from the inner part to the outer part; the pressure-relief gate is arranged on the outer side mouth of the joint cylinder body. The utility model has the advantages of simple structure, low cost and easy installation, and if the utility model is installed in the dust-collecting system, the original performance of the dust-collecting system can not be influenced; when the inflammable dust at the inner part of the dust-collecting system is exploded, the explosion pressure can be relieved, and simultaneously the flame of the air flow which relieved through the pressure-relief opening can be extinguished, and the possible generation of string fire and explosion outside the system is prevented.
Description
The utility model relates to a kind of dust-precipitating system pressure release flame-retarding fire-extinguishing device, can be widely used in each link of dust-precipitating systems such as dust arrester, separator, transmission pipeline network.
The collection of dust, carry, be separated in enterprise and be one and relate to the bigger system of working face, also Just because of this, the explosion accident of combustible dust is also a series of often, the quick-fried consequence of string combustion string is inestimable, so combustible dust is collected, carry, explosion-proof in the separation process just become one of related enterprise very sensitive issue, yet in the prior art, existing dust-precipitating system explosion precaution all is at dust collection, carry, the inner string combustion of the dust-precipitating system of separation string is quick-fried, to the dust-precipitating system explosion accident the system guest performer that may cause fire quick-fried the preventing of string and consider very few, as the disclosed dust-precipitating system explosion-protection equipment of Chinese patent CN2133372Y, though it can prevent the generation of the quick-fried accident of dust-precipitating system inner string combustion string effectively, but during to the dust-precipitating system internal explosion, what the system guest performer that the fireworks institute that reveals by explosion relief door may cause was fired the quick-fried accident of string prevents from just not add consideration.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and when providing the inner combustible dust of a kind of dust-precipitating system to blast, the blast pressure of releasing, can also extinguish simultaneously by pressure port release fireworks in the air-flow, prevent that the system guest performer that may cause from firing the dust-precipitating system pressure release flame-retarding fire-extinguishing device that the quick-fried accident of string takes place.
The purpose of this utility model can realize by such technical scheme: this dust-precipitating system pressure release flame-retarding fire-extinguishing device, it comprises interface cylindrical shell and the interior pressure port that is provided with every core body such as dust layer, " # " trellis fire extinguisher, the fire-retardant explosion suppression device of fence type and interface cylindrical shell lateral port that sets gradually from the inside to the outside thereof, described " # " trellis fire extinguisher by " # " trellis bag film and in fill the extinguishing chemical of putting and constitute.This dust-precipitating system pressure release flame-retarding fire-extinguishing device, be installed in the pressure relief opening that dust-precipitating system is offered, when the inner combustible dust of dust-precipitating system is blasted, dust fires bluster and promptly breaks through/fire the parcel bag every the extinguishing chemical of dust layer and setting of molten pressure release flame-retarding fire-extinguishing device, make the rapid diffusion of extinguishing chemical jump on the dust that passes through and fire bluster, cool off through the heat absorption of the fire-retardant explosion suppression device of fence type again, temperature promptly is lower than burning-point, then releases promptly by the pressure port of being opened by blast pressure compressing again and can not the initiating system guest performer fires the generation of the quick-fried accident of string.
Above-mentioned can make with plastic sheeting every dust layer; Also available woven cloth is made.
Above-mentioned " # " trellis fire extinguisher, its " # " trellis bag film can be made by plastic sheeting, and filling the extinguishing chemical of putting in it can be made of fire-fighting powder and inert gas.
The fire-retardant explosion suppression device of above-mentioned fence type can constitute by the multiple layer metal silk screen is compound; Also can make with metal fillings.
This dust-precipitating system pressure release flame-retarding fire-extinguishing device provided by the utility model, simple in structure, cost is low, settle easily, the primary characteristic that does not influence dust-precipitating system is installed in dust-precipitating system, and when the inner combustible dust of dust-precipitating system is blasted, the blast pressure of releasing, can also extinguish simultaneously by pressure relief opening release fireworks in the air-flow, prevent that the system guest performer that may cause from firing the generation of the quick-fried accident of string.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:
The internal structure schematic diagram of the dust-precipitating system pressure release flame-retarding fire-extinguishing device that Fig. 1 is provided for the utility model embodiment.
The internal structure schematic diagram of " # " trellis fire extinguisher of the dust-precipitating system pressure release flame-retarding fire-extinguishing device that Fig. 2 is provided for the utility model embodiment.
